A diagnostic challenge: eosinophilic cystitis, neurogenic bladder dysfunction, or both?

Eosinophilic cystitis is a rare inflammatory disorder, which may present with dysuria, haematuria, frequency, suprapubic pain and urinary retention. The findings may mimic other disorders like neoplasm, cystitis glandularis and neurogenic dysfunction. We report a case of eosinophilic cystitis in a 73-year-old woman, with spinal stenosis, who presented urinary retention, haematuria and overflow incontinence. Urodynamic study revealed a poor compliance bladder, with high grade vesicoureteral reflux. Cystoscopy with bladder biopsy confirmed the diagnosis.
